I am starting to get some insight into interactive plotting with python and matplotlib using pyGTK+. Therefore I took a look at the example given at the matplotlib website.
This is a short exerpt of the Code:
#!/usr/bin/env python """ Example of embedding matplotlib in an application and interacting with a treeview to store data. Double click on an entry to update plot data """ import pygtk pygtk.require('2.0') import gtk from gtk import gdk import matplotlib matplotlib.use('GTKAgg') # or 'GTK' from matplotlib.backends.backend_gtk import FigureCanvasGTK as FigureCanvas from numpy.random import random from matplotlib.figure import Figure
Ones I try to run this Script in the Terminal I get the following error:
Traceback (most recent call last): File "gtk_spreadsheet.py", line 15, in <module> from matplotlib.backends.backend_gtk import FigureCanvasGTK as FigureCanvas File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/matplotlib/backends/backend_gtk.py", line 33, in <module> from matplotlib.backends.backend_gdk import RendererGDK, FigureCanvasGDK File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/matplotlib/backends/backend_gdk.py", line 29, in <module> from matplotlib.backends._backend_gdk import pixbuf_get_pixels_array ImportError: No module named _backend_gdk
I have python 2.7 and pygtk 2.24 installed.
Can anyone figure out where the error is located? I think it might be connected to some linking issues?
Note that the Debian/Ubuntu package you need is not 'pygtk2-devel' but 'python-gtk2-dev':
sudo apt-get install python-gtk2-dev
should fix this error on these platforms.
